LOCK-UP Fon PRINTERS foams.

SPECIFICATION forming part of Letters Patent No. 380,597, dated April 3,1888.

Application lcd November l, 1G87. Serial No. 253,952. (No model.)

To alZ whom, it may concern:

Be it known that I, JACOB Bonson, of Milwaukee, in the county ofMilwaukee, and in the State of Visconsin, have invented certain new anduseful Improvements in Lock-Ups for Printers Forms 5 and I do herebydeclare that the following is afnll, clear, and exact descriptionthereof.

My invention relates to devices for locking up forms in type-beds orchases; and it consists in certain peculiarities of construction andcombination of parts, to be hereinafter described with reference to theaccompanying drawings, and subsequently claimed.

In the drawings, Figure l represents a plan View of my invention partlybroken away and in operative position; Figs. 2, 3, and 4, sections,respectively, taken on lines 22, 33, and 4 et of Fig. 1. Fig. 5 is anelevation of a key employed in connection with my device.

. Referring by letter to the drawings, A represents a printers chase,and B a form of type contained in said chase. Between one side of theform and the chase is arranged my locking device, the latter consistingof two parallel bars, C D, flanged upon their inner sides and united bypeculiar toggle-joints, that will be hereinafter described.

Pivot-ally connected to the dange c of the bar G, on each side thereofeqnidistant from its center, are the inner ends of plates E E F F,oppositely arranged in pairs, each pair constituting one section of atoggle-joint.

Pivoted between the plates E E and F F, at their outer ends, are therightangular ears g on the adjacent ends of bifurcated arms G, and theouter ends of these arms are in turn pivoted to the flange d of the barD, each of said arms constituting another section of a toggle- Theplates E E are provided with circular openings, in which fit the flangesh of an eccentric disk, H, the latter being loosely tted in the head ofa rack, I, and provided with a seat or opening, j, to receive a suitablekey. The plates F F are also provided with circular openings, and inthese openings is litted a round hollow casting, K, through which passesthe free end of the rack I. Integral with the casting K are arms M N,respectively arranged adjacent to the edges of the rack, the arm M beingprovided with teeth m to engage said rack, and the arm N has a lateralliange, n, that serves as a grip for the operator when it is desired toactuate said casting to ed'cct an engagement of said teeth.

Vhen a form B is placed in a type-bed or chase, my device is placed sothat whenspread apart the arm G thereof will bear against a side-stick,b, of the form and the arm D against one'side of the bed or chase. Theoperator now takes hold of the grip n on the arm N, and by a slightmovement of the same in an ontward direction causes a partial revolutionof the casting K to bring the teeth m. on the arm M into engagement withthe rack I, and thereby form a lock. A key, J, is now insertedin theseat or opening j in the disk H, and by a slight turn of this key ineither direction the rack I is actuated to canse a further spreading ofthe toggle-joints, whereby the bars G D are firmly bound against thechase or bed and typei'orm, and the latter thus locked up ready for theoperation of a press.

One or more of my locking-np devices may be employed, according tothesize of the chase and that of the form, and when aform islocked up ina chase and the latteris smaller than the type-bed of the press on whichit is desired to work said form one or more of my devices can beemployed to secure said chase and its contents on the type-bed.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. A device for locking up forms in typebeds or chases,that comprisestwo parallel bars, toggle-joints uniting the bars, a rack eccentricallyconnected to one of the joints, a cast ing pivoted to another of thejoints and pro-'- vided with a passage for the rack, an arm on thecasting for engagement with the rack, and suitable means for actuatingthis rack when engaged by the arm, substantially as set forth.

2. A device for locking up forms in typebeds or chases, that comprisestwo parallel bars, toggle-joints uniting the bars, a rack eccentricallyconnected to one of the joints, a hollow casting pivoted to another ofthe joints and provided with two arms, one of which constitutes a dog toengage the rack and the other a lever for actuating the casting to causesaid engagement, and suitable means for operating IOO ing K, having thearms M N, substantially as. set forth. I

In testimony that I claim the forego1ng I have hereunto set my hand, atMilwaukee, 1n I5 the county of Milwaukee and State of Wisc0n sin, in thepresence of two witnesses.

said rack when engaged. by the arm, substantially as set forth'.

3. A device for locking up formsin typebeds or chases, that comprisesthe parallel bars C D, plates E E F F, pivoted in pairs to the bar C andprovided with circular openings,- bfurcated arms G, pivoted to the bar Dand having ears g, pvoted in turn to the platesE E F F, the eccentricdisk H, provided with an opening, j, and flanges h, the rack I,havingits head 'L' loosely fitted on the disk, and the cast- Wi tnesses:
